8.5M full-text U.S. court opinions from 1658 onward to 26Q1. Case names, filing dates, citations, and ~86B characters of cleaned opinion text. One record per row in ready-to-import CSV format.
Overview
This dataset contains 8,507,968 full-text U.S. court opinion records spanning 38 decades of American jurisprudence, with the earliest opinion filed in 1658. Each record pairs the complete narrative opinion text with its case metadata, making the corpus suitable for legal NLP, language model training, citation analysis, and legal research applications. Opinion texts average roughly 10,000 characters (about 1,600 words), range up to 3.4 million characters for the longest opinions, and total approximately 86 billion characters of cleaned legal text.
Each record includes:
case_name — the name of the case
cleaned_text — full narrative opinion text, cleaned and whitespace-normalized
citations — the case's citations as reported
date_filed — filing date
citations_norm — normalized citation string for matching and deduplication
The data ships as a single UTF-8, RFC-4180 CSV (~81.5 GB) with a header row, exported directly from PostgreSQL for reliable reimport into any database or data pipeline. Every record contains non-empty opinion text — empty and whitespace-only entries have been excluded. Text fields preserve original paragraph structure (embedded newlines are properly quoted), and null values are distinguishable from empty strings on import.
